Thus itwill be seenthat each extension 16 forms a brace which bears against the exterior ofthe adjacent Winding midway between the end members 9. The portion ofthe winding thus supported is that most liable to distortion by thebulging out of the sides 01 the coils. As the body portion 15 of eachcoil support is included within the fieldmagnet structure, theconstruction is neat, compact and strong. By reason of the engagement ofthe inner end of each projection by the inner end of the adjacentprojection, the adjacent projections mutually support each other, thusmaterially adding to the strength and igidity of the arrangement.

It will be readily understood that the field magnet shown cooperateswith a suitable armature and that the usual means are employed forenergizing the windings of the clectromagnet.

I have not thought it necessary to illusirate these features in mypresent application as they are well understood in the art an d theirspecific embodiment forms no part of my present invention.
